express the confidence interval 0.38 p 0.54 in the form of p^ ± e
Answers
Answer 1
So, we have the interval 0.38 < p < 0.54: Assume that p is in the middle of the given interval: p = (0.54-0.38) / 2 = 0.08
Then, e can be calculated as follows: e = end of interval - p = 0.54 - 0.08 = 0.46
The required expression can be written as follows: p ± e = 0.08 ± 0.46

126 employees is 3% of what number of employees
Answers
First, define what it is that is being asked.
"of" in mathematics usually means that the numbers or values described are being multiplied.
And so the word problem becomes: 126 employees = 3% * x employees Solve:
126 = .03 * x x * .03 = 126 (x * .03) / .03 = 126 / .03
x = 4200 employees
Thus your answer is 4200 employees.
Your answer is 4,200 employees.
If 126 is equivalent to 3%, then we can say that 126/? = 3/100, which you can then use to find the answer by doing 126 ÷ 3 = 42, and then multiplying 42 by 100 to get 4,200.
